What are the key features of CD74AC652M96?
- 8-bit bidirectional registered bus transceiver with select input for multiplexed real-time and registered data paths in a single device
- Independent output-enable and direction controls on each port for flexible bus arbitration without external gating logic
- AC CMOS logic family with 50 pF load capacity in a 24-pin SOIC package enabling reliable bus driving at 3.3 V to 5 V
What is CD74AC652M96 used for?
The CD74AC652M96 is designed for high-speed bidirectional data bus isolation and buffering in microprocessor and DSP systems where registered and real-time transmission modes must both be supported from a single IC. Its select input allows designers to switch between latched and transparent operation without external multiplexers, reducing logic complexity in memory interface and peripheral bus designs. The AC CMOS family's low propagation delay and 50 pF load rating make it suitable for address and data bus buffering in embedded systems, FPGA I/O expansion, and backplane interface circuits.

Frequently Asked Questions
What is the difference between the registered and real-time transmission modes of CD74AC652M96 and when should each be used?
In real-time (transparent) mode, data flows directly from the input port to the output port with only propagation delay (typically under 10 ns at 5 V, 50 pF load) — suitable for asynchronous bus connections where no latching is required. In registered mode, an internal 8-bit latch captures data on the clock edge, holding the output stable while the input bus changes — ideal for synchronous processor-to-memory interfaces where address or data must be held valid for multiple clock cycles. The CD74AC652M96's select input switches between these modes at runtime, letting a single device serve both purposes in a multiplexed bus architecture.
How does CD74AC652M96 simplify bus arbitration in a dual-processor shared-memory board design?
In a dual-processor shared-memory design, the CD74AC652M96's independent direction and output-enable controls on each port allow each processor to drive the 8-bit bus only when granted bus mastership, while the other processor's port is tristated. This eliminates the need for 4 to 8 separate discrete bus switches or buffer ICs, consolidating 8-bit bidirectional control and latching into a single 24-pin device and reducing propagation delay in the arbitrated bus path compared to cascaded discrete components.
Can CD74AC652M96 directly interface 3.3 V FPGA I/O with a 5 V peripheral bus without additional level shifters?
The CD74AC652M96 in the AC CMOS family is a 5 V-powered device; its input thresholds require approximately 3.5 V high-level input when powered at 5 V, which 3.3 V FPGA outputs (driving 3.0 V to 3.3 V) may not reliably meet. A level shifter or a variant powered at 3.3 V is required for clean 3.3 V to 5 V translation. However, when both the FPGA and peripheral bus operate at the same 3.3 V or 5 V level, CD74AC652M96 serves as a direct interface requiring no additional translation components across its 8 bidirectional data lines.
